Compton scattering
Let an agent explain Compton scattering, relay the physics, formula and applications from physics sources, describe its roles in imaging, radiation shielding and astronomy, and distinguish Compton scattering from Thomson and Rayleigh scattering, the photoelectric effect, pair production and inverse Compton scattering.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain Compton scattering, relay the physics, formula and applications from physics sources, describe its roles in imaging, radiation shielding and astronomy, and distinguish Compton scattering from Thomson and Rayleigh scattering, the photoelectric effect, pair production and inverse Compton scattering.
The inelastic scattering of a photon, usually an X-ray or gamma ray, by a charged particle, typically an electron, in which the photon transfers energy and momentum to the electron and emerges with a longer wavelength, the shift depending on the scattering angle by the Compton formula; discovered by Arthur Compton in 1923, it provided key evidence for the particle nature of light and matters in radiation physics, medical imaging and astrophysics.
What it is for: Not applicable; a physical process.
It can be explain the process; relay formula and history; describe applications; distinguish related processes.
Distinguishing features
Inelastic
Wavelength shift
Particle nature of light
Important in radiation physics
What it looks like
Not a visible object; a particle interaction.
Physical character
Compton wavelength of electron: about 2.426 x 10^-12 m
discovered: 1923 year - Arthur Compton
Nobel Prize: 1927 year
dominant interaction in tissue: about 0.1-10 MeV - approximate range
How it is recognised
Inelastic photon-electron scattering
Compton effect, Compton shift
Thomson scattering is elastic low-energy; Rayleigh is by bound atoms; the photoelectric effect absorbs photons; pair production creates particles
